What powers the car air conditioning?

[NatalieLee]

Car air conditioning is powered by the generator. Below is a detailed introduction to the components of the car air conditioning system: 1. Air conditioning pressure sensor: Usually installed after the dryer, it is used to detect the hydraulic pressure of the liquid refrigerant flowing through the expansion valve. There are three wires: detecting high and low pressure. When a car collision causes refrigerant leakage and compressor oil loss, to prevent compressor damage due to lack of oil, the compressor power is quickly cut off once low pressure is detected. When high pressure is detected, the compressor power needs to be reduced to avoid wasted work. 2. Air conditioning temperature sensor: Typically located inside the temperature sensing package, it is the evaporator temperature sensor. When the cooling reaches a certain level, the compressor needs to be shut down to prevent frost formation and eventual ice blockage. 3. Air conditioning compressor relay: Generally installed on the compressor, it controls the start, stop, and power switching functions of the compressor.
